# LlamaIndex SDK

> Use LlamaIndex through Keywords AI

<Note> This integration is for the **Keywords AI gateway**. </Note>

## Overview

LlamaIndex provides a powerful framework for building LLM applications with data. You can seamlessly integrate Keywords AI with LlamaIndex's `OpenAI` LLM with minimal code changes.

## Quickstart

### Step 1: Install LlamaIndex

<CodeGroup>
  ```bash Python theme={"system"}
  pip install llama-index-llms-openai
  ```
</CodeGroup>

### Step 2: Initialize LlamaIndex with Keywords AI

<CodeGroup>
  ```python Python theme={"system"}
  from llama_index.llms.openai import OpenAI

  llm = OpenAI(
      api_base="https://api.keywordsai.co/api/",
      api_key="<Your Keywords AI API Key>",
      model="gpt-3.5-turbo"
  )
  ```
</CodeGroup>

### Step 3: Make Your First Request

<CodeGroup>
  ```python Python theme={"system"}
  response = llm.complete("Hello, world!")
  print(response)
  ```
</CodeGroup>

## Switch models

<CodeGroup>
  ```python Python theme={"system"}
  # OpenAI GPT models
  model = "gpt-4o"
  # model = "claude-3-5-sonnet-20241022"
  # model = "gemini-1.5-pro"

  llm = OpenAI(
      api_base="https://api.keywordsai.co/api/",
      api_key="<Your Keywords AI API Key>",
      model=model
  )
  ```
</CodeGroup>

<Note>
  See the [full model list](https://platform.keywordsai.co/platform/models) for all available models.
</Note>

## Supported parameters

### OpenAI parameters

We support all the [OpenAI parameters](/api-endpoints/develop/gateway/chat-completions#openai-compatible-parameters). You can pass them directly in the LlamaIndex configuration.

<CodeGroup>
  ```python Python theme={"system"}
  llm = OpenAI(
      api_base="https://api.keywordsai.co/api/",
      api_key="<Your Keywords AI API Key>",
      model="gpt-4o-mini",
      temperature=0.7,          # Control randomness
      max_tokens=1000,          # Limit response length
  )
  ```
</CodeGroup>

### Keywords AI Parameters

[Keywords AI parameters](/api-endpoints/develop/gateway/chat-completions#keywords-ai-parameters) can be passed using `extra_body` for better handling and customization.

<CodeGroup>
  ```python Python theme={"system"}
  response = llm.complete(
      "Tell me a story",
      extra_body={
          "customer_identifier": "user_123",           # Track specific users
          "fallback_models": ["gpt-3.5-turbo"],       # Automatic fallbacks
          "metadata": {"session_id": "abc123"},        # Custom metadata
          "thread_identifier": "conversation_456",     # Group related messages
          "group_identifier": "team_alpha",           # Organize by groups
      }
  )
  ```
</CodeGroup>
